toJson method

  1. @override
Map<String, dynamic> toJson()
override

Abstract function that concrete classes must implement. This must encode the internal data model to a JSON compatible representation.

While not required, it is suggested to call removeNull before returning.

Implementation

@override
Map<String, dynamic> toJson() {
  return JsonClass.removeNull({
    'alignment': ThemeEncoder.encodeAlignment(alignment),
    'boundaryMargin':
        EdgeInsets.zero == boundaryMargin
            ? null
            : ThemeEncoder.encodeEdgeInsets(boundaryMargin),
    'clipBehavior':
        Clip.hardEdge == clipBehavior
            ? null
            : ThemeEncoder.encodeClip(clipBehavior),
    'constrained': true == constrained ? null : constrained,
    'interactionEndFrictionCoefficient':
        0.0000135 == interactionEndFrictionCoefficient
            ? null
            : interactionEndFrictionCoefficient,
    'maxScale': 2.5 == maxScale ? null : maxScale,
    'minScale': 0.8 == minScale ? null : minScale,
    'onInteractionEnd': onInteractionEnd,
    'onInteractionStart': onInteractionStart,
    'onInteractionUpdate': onInteractionUpdate,
    'panAxis':
        PanAxis.free == panAxis ? null : ThemeEncoder.encodePanAxis(panAxis),

    'scaleEnabled': true == scaleEnabled ? null : scaleEnabled,
    'scaleFactor':
        kDefaultMouseScrollToScaleFactor == scaleFactor ? null : scaleFactor,
    'trackpadScrollCausesScale':
